What it isAlbumin is the most abundant protein in blood plasma, manufactured exclusively by the liver. It functions as the body's primary carrier of fatty acids, hormones, calcium, drugs, and bilirubin.

DoesMaintains oncotic pressure to keep fluid inside blood vessels; transports a vast array of molecules; serves as a circulating amino acid reservoir.

GoodHigh-normal albumin signals robust liver synthesis, adequate protein nutrition, low inflammation, and is one of the strongest single predictors of longevity.

BadLow albumin marks chronic inflammation, malnutrition, liver disease, kidney protein loss, or frailty. It predicts mortality across nearly every disease category.

Standard
3.5–5.0 g/dL.
Optimal
4.5–5.0 g/dL (higher is good within range)
Modifiers
Falls with inflammation (acute-phase response), aging, hospitalization; dehydration falsely raises it.

How to optimize

Lifestyle
Resistance training to maintain lean mass; avoid prolonged inactivity.
Diet
Adequate protein intake (1.2–2.0g/kg body weight); whole-food protein sources — eggs, meat, fish, legumes; address gut malabsorption.
Supplements
Whey or collagen protein if intake is low; essential amino acids; address underlying inflammation drivers.
Peptides
BPC-157, GHK-Cu may support liver synthesis indirectly.
Drugs
Treat underlying disease; no direct pharmacologic lever.
